To all whom 'it may concern' Be it. known that T, HENRY B. CooLnY, acitizen of the United States, andresidentof New Britain, in the countyof Hartford and State of (ounecticuh-have invented a new and useful Type-Chase and Form-Cylinder for Printing-Presses, of which the followingis a specification.

My invention relates to a type chase and form cylinder for printingpresses with the object in view of providing 'asuhst-antial support forthe chase both edgewise and at the back so that the type or furnituremay be securely locked in the chase without danger of springing thechase and for the ready removal and replacement of the chase and forholding it securely in position.

The type of cylinder which I have chosen to illustrate my invention is arota-ry flat bed cylinder and is shown as having two oppositely disposedflat beds separated by cylindrical segments.

In the accompanying drawings. Figure l is a view of the form cylinder inelevation showing the type chases in edge ele. at ion, Fig. 2 is a viewtaken-in a plane at right angles to that of Fig. 1, showing a partialplan view of one of the type chases, Fig. 3 is a transverse section inthe plane of the line AA of Fig. 1, showing the chase retaining slidesclosed, Fig. 4 is a partial section in the same plane showing a chaseretaining slide open, Fig. 5 is a view of the same in elevation, andFig. 6 is a plan view of the same.

The form cylinder is denoted as a whole. by t. it is provided with twooppositely disposed tlat beds 2 and 3, separated at the periphery of thecylinder by cylindrical seg ments 4 and The type chases to be re.-ccivcd on the beds 9 and 3 are denoted by (3 and 7. respectively. Theyare quite similar in structure and a description of one will sullice forboth. Referring to the cease 6, its end edgesare beveled, as shown at 8and 9, to lit. and slide in undercut grooves 10 and 11 in the rims atthe opposite ends of the cylinder. The rear and front edges of the chaseare also beveled, as shown at 12 and 13, to fit the inwardly directedslanting faces of the keepers a t rear and front. The

rear edge 12 of the "chase is recessed at its TYPE-CHASEAnnronM-cYLrNnERFoR PRINTING-PRESYSES,

' The fixed keepers for receiving tht front edge 13 of the chaseconsistsof thin plates 16, 17. 'lheseifixed keepers are curved toconform to the curve of the cylindrical-segment and project beyond theface of the bed 2 a distance preferably about the thicknelss of thechase.

The sliding keepers for the chase 6, are denotedby 21, 22. They are each provided with one or more, in the presentinstance with one, elongated shouldered slot 23 through which a setscrew'24 extends, the under face of the head of the screw engaging theshoulder within the slot. The sliding movement of the sliding keepers issutiicicnt to permit the end of the keeper to overlap the beveled edgeof the chase to an extent preferably equal to the thickness of thechase. Both the fixed and the sliding keepers are let into thecylindrical segments of the cylinder a distance suilicient to bringtheir outer faces substantially flush with the outer face of thesegment. and the Walls of the cutaway portions of the segments in whichthe slid ing keepers are seated serve to guide the said keepers in theirsliding movements.

The number of screws for holding the keepers in position is a matter ofchoice, and slight changes might heresorted to in j invention. i What Iclaim is I I 1. The combination with a form cylinder They are each-secure'd in Each cylinder segment has fixed keepers at.

4. In combination, a flat type chase prw videdwith beveled edges andwith recesses at one edge, a form cylinder provided with a flat chasebed and cylindrical segments at the opposite edges of the bed, the saidbed having undercuts at its opposite ends to receive the ends of thechase, fixed keepers seated in one cylindrical segment and slidingkeepers seated. in the opposite cylindrical segment in position to enterthe reeesses at the edge of the chase.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of two witnesses, this 21st day of January 1910.
